OPTRA’s two-band digital micromirror device (DMD) based IR scene projector enables realistic simulations of midwave infrared scenes for training and test of IR imaging systems. This system offers excellent image uniformity, 100% pixel operability, and high apparent temperatures. We have recently developed a next generation scene projector with unprecedented dynamic range in the form of infinite bit depth independent of frame rate and 4000:1 contrast. We also have concepts in place for extending the spectral range from the ultraviolet through the longwave infrared with the addition of a third channel.
